Question

The market price of a​ company's stock dropped ​$5 per hour for 4 hours. Write this information using integers and find the total points the stock fell.

Answer 1

Using integers to represent the market price change, a drop of $5 per hour over 4 hours is denoted as four instances of -5. By multiplying -5 by 4, the total change in stock price is an integer of -20, reflecting a $20 total decrease.

Step-by-step explanation:

To represent the stock price change using integers, we denote the drop in price per hour as -5. Since the stock price dropped $5 per hour for 4 hours, we have four instances of -5. To find the total points the stock fell, we can sum these integers.

1. Multiply the drop per hour (-5) by the number of hours (4).
2. -5 × 4 = -20

Therefore, the total points the stock fell is represented by the integer -20.
